A deep-dive digital review focused entirely on domain and range — covering all representations (graphs, tables, ordered pairs, equations) across multiple function types including piecewise functions. Includes an interactive 9-function graph explorer. ★ WHAT'S COVERED • Domain & Range from graphs — using arrows, endpoints, open/closed dots; continuous vs. discrete; reading x-extent and y-extent • From tables and ordered pairs — set notation, listing all x and y values • From algebraic rules — ide
